Preschoolers' (60 boys and 64 girls, "M" age = 50.73 months) affiliations with prosocial peers were observed in naturally occurring interactions and then examined in relation to positive and negative emotionality within their peer interactions one semester later. Greater affiliation with prosocial peers in the fall was related to enhanced positive…

The developmental trajectories of attention focusing (by parents' and teachers' reports) and attentional and behavioral persistence (observed during a laboratory task)--2 indexes of effortful control--and externalizing problems from ages 5 to 10 years were examined for 356 children combined from a pair of 3-wave (2 years apart) longitudinal…

The relations of children's internalizing and externalizing problem behaviors to their concurrent regulation, impulsivity (reactive undercontrol), anger, sadness, and fearfulness and these aspects of functioning 2 years prior were examined. Parents and teachers completed measures of children's (N = 185; ages 6 through 9 years) adjustment, negative…

The relations of children's nonsocial behavior to their emotionality, regulation, and social functioning were examined in a short-term longitudinal study. Parents (primarily mothers) and teachers rated children's effortful regulation, emotionality, asocial behaviors, problem behaviors, and social acceptance, and children's nonsocial play behaviors…

In this study, the linear and interactive relations of children's effortful control and parents' emotional expressivity to children's empathy-related responses were examined. Participants were 214 children, 4.5 to 8 years old. Children's effortful control was negatively related to their personal distress and was positively related to their…

Examined relations of effortful control and ego control to children's resiliency, social status, and social competence concurrently (Time 3) and over time. Found that at Time 3, resiliency mediated the unique relations of effortful and reactive control to social status, and effortful control directly predicted socially appropriate behavior.…

Examined the role of same-sex peer interactions in influencing early school competence and the degree to which effortful control (EC) moderated these relations. Results indicated that EC, measured at the end of the Fall semester, moderated the relations of children's same-sex play to their school competence, measured at the end of the following…

Examined relations between mothers' expressed positive and negative emotion and 55- to 79-month-olds' regulation, social competence, and adjustment. Structural equation modeling revealed unique effects of positive and negative maternal expressed emotion on children's regulation, and the relations of maternal expressed emotion to children's…

Examined whether preschool children's play-partner choices were stable over time and how they influenced behavior. Found that partner preferences were highly sex differentiated and stable over time. Identified two types of consequences of partner choice: a binary effect that influenced differences between the sexes and a social dosage effect that…

Guided by the heuristic model proposed by Eisenberg et al. [Psychol. Inq. 9 (1998) 241], we examined the relations of mothers' reported and observed negative expressivity to children's (N = 159; 74 girls; M age = 7.67 years) experience and expression of emotion. Children's experience and/or expression of emotion in response to a distressing film…

The study of children?s peer relationships has been well represented within the pages of Merrill-Palmer Quarterly. Particularly over the last decade, the pace of publishing studies on peer relationships has increased. Despite this upswing in interest in peer relationships, significant gaps remain. In this article, we focus on a particularly…

Studied relationship of temperament and same-sex peer interaction with gender differences in adjustment. Found that highly arousable boys who played with same-sex peers had increased problem behaviors. Arousable girls who played with other girls were relatively unlikely to show problem behaviors. The arousability and same-sex peer interaction…

Preschoolers were accurate in identifying the situational determinants of others' real emotions. Their strategies for remediating negative affect in others were consistent with the type and attributional basis of the emotion to be altered. Further, they used contextual information in significantly different and meaningful ways across and within…

Examined the relation between 72 mothers' attitudes and practices regarding the use of rewards and their second- through fifth-grade children's susceptibility to the undermining effects of rewards. It was suggested that children's responses to rewards depend in part on their experiences with rewards. (RJC)

Mothers of 49 kindergartners and 54 second graders told their children 2 stories about distressed persons to obtain children's emotional, physiological, and prosocial responses. For kindergartners, mothers' perceptions of children's emotional reactivity were positively related to their use of positive facial expressions, whereas mothers'…
